To all whom it may concern:

Be it known that I, EUGEN Snrrz-, a subject of the King of Hungary, residing at Budapest, in the Kingdom of Hungary,

have invented certain new and useful Imrovements in Machines for the Automatic gpreading and Filling of Waffle Leaves One Above the Other (for which I have iiled applicationsin Hungary, Mar. 31, 1914, Patent No. 711,112, and in Germany Mar.28, 1914, Patent No. 313,695), of which the following is a specication. d Y

This invention relates to improvements in machines for spreading coating or illing material on wafers or plates such, for instance, as waille leaves and the invention has for its object to provide a machine which permits of the wafers or plates' to be coated with any desired mass and stacked one above the other with great rapidity and economy of material and power consumption and by which broken wafers may also be covered and the thickness of the layer of material varied as desired. l

The machine consists essentially of a slide provided with a hopper for supplying the material which is reciprocally actuated from theV power source above a wafer plate receiving cavity provided in the work table, the reciprocation of the slide automatically effecting step by step variations in the depth of the cavity for the production of cakes of varying thickness.

With these and other objects in view'thel terial to be appliedl to the wafer issupported on the frame structure 2 constitutin a base. Ay cavity in .which the wafer p ates are placed preliminary to the application of the paste or other material thereto is provided in the work table and a plate 3 is guided vertically in the cavity and its position may be varied by adjustment of the wedge 4 upon which said plate is supported. A hopper 5 having a suitable lining 6 is arranged on a slide 7 mounted on the work table 1 and in which the maplates is contained.

The slide 7 is provided with side members 8 which engage the work table and guide the movement of the slide.

The slide 7 is 'positively actuated longitudinally by two rods 9 and connecting rods 10, the latter beingconnected to a disk 11 actuated from a lsuitable source of power. The upper ends 12 of the rods are connected with the slides 7 by two pins 13 which latter support pressure rollers 14 confined between the 'extremities of the rods and the slide. The central apertured portions 15 of the rods are pivotally connected with the connecting rods 10 at 16.V The lowerv rod ends y17 are connected together by a shaft 18 upon whichare mounted two guide rollers 19 which latter are mountedto travel between tracks 20' `provided on the frame structure 2 and thereby insure vertical movement of the lower extremities of the rods 9.

The disk 11 receives movement through a suitable gear 24, 26 and through a belt pulley 27.

Two angle levers 29 and 30 connected together by rods 38 are arranged in pairs on -each side of the base, the stroke of the lower arm of each lever 30 being limited by a contact member 31. The angle levers 30are connected with the levers 33 by rods 32 and the upper ends ofthe levers 33 are provided with a pawl 35 engaging a ratchet bar 36 carried by thev draw rod 37 which latter is slidable ini-supports 47 and guided in a recess in a contact member 48.

SFREADING- AND FILLING 0F WAF'IYLE LEAVESONE ."7 ABOVE THE OTHER.' l

A cross head 39 attached to the lever 30 is actuatedby means of a screw bolt 40 which, in turn, is actuated by the bevel gears 4l. rlhe pivoted extremities off the rods 32 and levers 33 are connected with a contractile spring 46, the opposite extremity of which is connected at 67 with the traine structure 2. rlhe upperY plate 3 of the receiving cavity is connected with a lower plate 49 by means ot connecting bolts 50 which pass through guides 5l secured to the work table between the two plates. center bolt 53 is secured to the lower plate 49 and passes through a guide element 54 attached to the base. At its lower end, the center bolt is connected through a universal joint 55 -with a medial odset lever rod 56 which latter is connected with any preferred type of foot pedal 58. l

A guide pulley 6l is supported in the frame structure 2 and partially supports a cable having a weight 59 attached to one end and connected at its opposite end at 63 to a depending bracket `62 carried by the draw rod 37. A pawl 64 is pivotally attached at 65 to the table l and is movable over the teeth of a ratchet bar 36. A set screw 77 is threaded in the bracket 62 and is engaged at one end with a plate 48 and provided at its opposite end with a handle 78.

A suitable type of force feed' mechanism 82 for the filling material is constructed and arrangedto deliver material into the open upper end ot the movable hopper 5 in predetermined quantities and the force feed device is connected with a main reservoir 69 preferably equipped with an agitator 8l and a heater 80. 'lhe'torce feed device may be actuated by the angular-lever 30 through suitable connections indicated at 86-85 and' 87. Y

The operation of the machine is as follows: V

The slide 7 carrying the hopper 5 therewith is reciprocated longitudinally ot' the table l during rotation of the disk 1l through the rods 9 and l0. When the slide moves across the cavity in which the water plate is located, the material is spread over the water plate and as the slide approaches the limit of its travel to the, left, in Fig. l, the rollers 14 engage and depress the upwardly inclined portions of the levers 29 thereby exerting a pull on the rods 38 which transmit the movement ot the levers 29 to the rods 36 and thence through the rods 32 toV thelevers 33. The disposition of the Vseveral levers'and rods is such that during depression of the upper extremities'of the levers 29 the upper extremities of the levers 33 are moved to the right, in lFig. l,

andthe pawl 35 coacting with theteeth of the ratchet bar 36 shift the wedge 4.and, owing to the angle of inclination of the upper face of the latter, the plate 3 drops a distance, according to the extent'ot movement of the wedge, 4. rlhe stroke or" the lever 33 may be varied with respect to the stroke .oit the lever 30 by proper adjustment of the cross head 39; through the screws 40 and accordingly the length of each individual movement'ot the ratchet bar and wedge 4 the other, the wedge 4 and plate 3 are re-v turned to initial position by actuating the pedal 58 which, through the rod' 56 and center bolt 53, raise the'plates 3 and 49. Simultaneously with the return of the plates and 49 to initial position, the wedge 4 isv returned to its initial position by the pull exerted by the weight 69 and cable 670 on the draw rod 37. i y l The plate 3 even in its initial position,

does not lieY flush with the top face ot the. L

table l but lies in a plane a proper distance below the plane of the 4table whereby to accommodate. thel first wafer plate to be covered orcoated and the initialposition of the plate 3 with respect Vto the top face of the table l may be varied by proper manipulation ot the screw 77 which, abutting the stop plate 48, is capable of shifting the draw rod 37 and the wedge 4 tothe left so as to permit the plate 3 to descend to the desired position. Y v
